Eco-Bloks: 100% Recycled Rubber "Sandbags"

Eco-Bloks are being billed as a environmentally-friendly replacement for sandbags. They are made with 100% recycled rubber tires — each block uses the rubber from approximately two passenger car tires. The use of sandbags has come under question recently, because of new clean water and storm water regulation. Unlike sand bags, which break and fall apart, Eco-Bloks are manufactured to last for years, according to the company. The blocks interlock and can be stacked, glued or staked in place. There are various versions of the Eco-Blok, including one that allows water to filter through, and a flexible bagged version. :: Ecoblok via Ecofriend
